Extension fails on ARM

[bradcla]

Issue Description

I have tried this with dotnet 3.1, dotnet 3.0 and now dotnet 2.2. I have a Raspberry Pi 4 running Raspian Stretch configured with key authentication. I am getting the following error;

[ERROR] Error: spawn /home/pi/.vscode-server/extensions/ms-vscode.csharp-1.21.10/.omnisharp/1.34.10/run ENOENT

The .omnisharp directory does not exist.

I even went back to an older version of OmniSharp to see if that would resolve the issue.

I am doing development from Windows 10 using VS Code. When I install the extension the above error is reported in the OmniSharp log.

Steps to Reproduce

I reinstall from the same Raspian disk image before attempting any of the above variants.

Expected Behavior

I expect OmniSharp to install properly and simplify my development process.

Actual Behavior

Error is reported when extension is installed on remote server.

This extension will not work on ARM.

OmniSharp doesn't support ARM at the moment. We discussed this recently and it may be feasible to add it though.
